updated to new automake and refactored server stuff. the server

now speaks to the primary screen and secondary screens almost
everywhere the same way through an IClient interface;  only
special primary screen calls are accessed through a different
interface, the CPrimaryClient interface.  this simplifies the
server since it no longer needs to test whether the active screen
is the primary or a secondary in most cases.

the server no longer speaks directly to the primary screen;  all
that goes through the CPrimaryClient, which often just forwards
the call.  the primary screen no longer speaks directly to the
server either, again going through the CPrimaryClient via a
IPrimaryReceiver interface.

CServerProtocol classes have been replaced by CClientProxy
classes which are very similar.  the name makes more sense
though.

## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the `deleted header file' problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.

maybe another device type: {data, state, repeat}
must handle on-the-fly addition/removal of devices how does negotiation proceed?
USB allows hotplugging and we should support, say, an added joystick could have sequence of queries and replies:
server -> client -> server ... end
client -> server -> client ... end
or a sequence of messages:
server -> client ... end
client -> server ... end
probably go with latter because it's more efficient but make it
3-way:
client -> server ... end
server -> client ... end
client -> server ... end
first messages from client must be version and name. the server
can create the appropriate protocol object right away then.
must have device negotiation example: clipboard formats:
at very least it negotiates mouse/keyboard at start # CNEG = negotiation command CNEG%s%s
# CNGE = end of negotiation command
# cbfa = clipboard, format, add (permitted format)
# cbia = clipboard, id, add (clipboard with id exists)
client -> server: CNEG "vers" "1.0"
client -> server: CNEG "name" "foobar"
client -> server: CNGE
server -> client: CNEG "cbfa" "text/plain/LF"
server -> client: CNEG "cbfa" "image/BMP"
server -> client: CNGE
client -> server: CNEG "cbia" "0"
client -> server: CNGE
server should just ask CProtocol (renamed from CServerProtocol) to
return a protocol. CProtocol should do negotiation, create the
appropriate protocol object, finish negotiation, and return the
new protocol object. unless connection is registered with server,
though, we can't save any screen info. perhaps CProtocol should
also return a screen info object or that should be part of the
protocol object (currently the protocol is part of the screen info).
if screen info is available to CProtocol then it should finish with
requesting the screen info, waiting for and then handling the reply.
the server can then just ask CProtocol for the protocol object then
add it to the connections.
maybe call the protocol types CClientProxy since that's how the
server uses it: as a stand-in for the client object. the interface
should closely reflect the CClient interface. do the reverse for
a server proxy for the client. maybe even have interface classes
for the client and server methods.

maybe config file can list format shared libraries to load. user
can then pick formats to support. but why would you ever want
fewer formats?
should the major burden of translation be on client or server?
probably client since it knows the formats preferred by the
platform and may be able to use platform utilities to convert.
server would then just support formats that minimize loss of
information.
desired formats to support:
text (LF)
text with character set
unicode (LF)
rich text (or some kind of formatting)
bitmap (BMP, PNG?)
sound (WAV)
note that formats should be added to the win32 clipboard in the
order of most descriptive to least because they're kept in order
and apps will generally use the first suitable match.
